Application filed September 18, 1907. Serial No. 393,544.

To all whom it may concern.'

Be it known that I, J Ess F. HINCK, a citizen of the United States,residing at Crookston, in the county of Polk and State of Minnesota,have invented certain new and useful Improvements in Wagon-Scales, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention relates to improvements in wagon scales, the object of theinvention being to improve the construction of a wagon scale of thischaracter and thereby render the same stronger and more durable, lessexpensive, and more convenient in the application to and removal fromthe wagon.

With the above and other objects in view which will appear as theinvention is better understood, the same consists in the novel featuresof construction, and the combmationV andv arrangement of partshereinafterv described and claimed, and illustrated in the accompanyingdrawings, in which,

Figure 1 is a side elevation of the wagon showing the application of theinvention thereto, the wheels' upon the near side of the wagon beingremoved. Fig` 2 is a top plan view,v Fig. 3 is a transverse sectiontaken on the plane indicated by the line 3 3 in Fig. 2, Fig. 4 is adetail perspective view of several of the levers of the device. Fig. 5is a view similar to Fig. 1 showing the removable parts of the device orattachment removed from the wagon, Fig. 6 is a perspective of one of thefulcrum carrying castings, Fig. 7 is a similar view of one of thefulcrum blocks, Fig. 8 is a perspective view of one of the castings whicconnect the members of the body supporting levers, Fig. 9 is aperspective view of one of the jacks for supporting the body, and Fig.10 is a detail perspective view of one end of one of the longitudinallevers.

In the drawings 1 denotes the running gear of a farm wagon, or othersuitable support, and 2 denotes the body of a farm wagon, or any othersuitable weighing receptacle. As shown, the running gear comprises areach 3 connecting the bolsters 4, 5, on the front and rear axles. Onthebolsters are arranged the usual stakes 6 which receive the wagon body2 between them and prevent the lateral movement of the same. The body isprevented from shifting endwise or longitudinally by the usual cleats 7arranged upon its bottom. The improved scales comprise a transverselever 8 and four longitudinal levers 9 which are arranged in pairs onopposite sides of the transverse lever and are adapted to receive andsupport the body 2 when the scales are being used. The levers 9 of eachpair are arranged in converging relation and The supports orl As clearlyshown in Fig. 6, each of the i fulcrum supports 10 is of substantial U-shape and has in one of its depending ends a set screw 12 to clamp it tothe bolster and, upon its other depending end a recessed enlargement 13to receive a fulcrum block 14. The block 14, as shown in Fig. 7, has achanneled upper surface to receive the fulcrum pin, and its bottomportion is of such shape that it may be readily inserted in and removedfrom the cavity in the enlargement 13.

In order to more effectively retain the block in its seat it is providedwith 'a pin 15 adapted to project into and through an aperture or socket16 in the enlargement, as will be readily understood upon reference toFigs. 6 and 7. On the outer end of the enlargement 13 is an upwardlyprojecting lug 17 arranged in front of the fulcrum block and projectingabove the same. The diverging ends of the levers 9 are bifurcated andrecessed upon their under sides and also have apertures 18 whichcommunicate with the recesses and are adapted to loosely receive thelugs 17. Arranged transversely in these recessed ends of the levers arefulcrum pins which are adapted to rest in the grooves or seats in thetop of the fulcrum blocks. From the foregoing it will be seen that thisconstruction permits the levers to be readily engaged with anddisengaged from the fulcrum supports, and that the latter are soconstructed that they may be readily mounted on a wagon of almost anysize and construction.

The converging inner ends of the body supporting levers 9 may bepermanently connected, if desired, but they are preferlablyy detachablyconnected by a coupling member 2O which is also adapted to removablyengage a transverse pivot 21 on the lever 8. The coupling and pivotmember 20 is preferably in the form of a casting, as shown in Fig. 8,and it comprises a plate or body formed at its center with a lug 22apertured to receive the pivot 21 and adjacent to its ends with upwardlyprojecting pins or studs 23 to enter the apertures 24 formed in theconverging ends of the levers 9. One of the coupling members 2O isprovided upon each side of the lever 8 for each pair of levers 9 andthey enable said levers to be quickly and easily'connected up for useand as readily disconnected so that the parts of the device may becompactly folded.

The levers 9 support the body 2 through the instrumentality of atransverse supporting bar or rod 25 arranged beneath said levers andadapted to be slipped into and out of openings in hangers or links 26which have their reduced ends projecting into openings 27 formed in thelevers 9 and permanently pivoted in said openings by transverse pivotpins, as more clearly shown in Fig. 4. In

order to support the body 2 from the rod 25 an adjustable connectingdevice is preferably provided, and which is here shown in the form of apair of screw jacks mounted upon a cross bar 29 which is adapted to bedetachably connected to the body 2. Each of said jacks consists of aright-angular body 30 having a horizontal arm 31 adapted to be securedto the cross bar 29 and formed upon J: its bottom with a boss 32containing a screw threaded socket to receive a screw 33 projecting fromthe plate or head 34 which is adapted to rest upon or engage one of therods 25. The body 30 of the jack is also formed with a vertical armcontaining a set screw by means of which the cross bar is removablysecured to the body 2.

It will be understood that the cross bar 29 is attached to the bottom ofthe body immediately above one of the rods 25, and the screws 33 arethen adjusted so that when the scales are used the body will beelevated. It will be further noted that the provision of the jacks ortheir equivalent adjustable connections, enables the device toaccommodate itself to wagons having bolsters and bodies of differentsizies.

The transverse lever 9 is fulcrumed at one of its ends upon a support 37which is adapted to be readily engaged with and removed from the wagon.This fulcrum support 37 preferably comprises a chain having at its upperend a hook 38 to take over the upper edge of one side of the body 2 andat its lower end a yoke 39 containing the fulcrum pin for the lever 8.This yoke 39 is preferably formed at its top with a hook 40 to engageone of the links of the chain 37 so that the latter may be detachablyand also adjustably connected to the yoke 39. A similar yoke 41 ispivoted to the other end of the lever 8 and has at its top a hook 42 toreceive a link, chain, or other flexible connection 43 which has itsupper end attached to a yoke 44. The latter is )ivoted to a graduatedscale beam 45 whic i is fulcrumed upon a hanger or support 46 and has atone of its ends a hanger 47 for the usual removable weights. The hanger46 is preferably of right-angular form7 as shown, so that its horizontalupper portion forms a support or shelf on which the weights may besupported. This support ,46 is adapted to be readily applied to andremoved from the wagon body and it is preferably provided with hooks 48which are adapted to take over the upper edge of one side of the bodyand which are flexibly connected as at 49 to said support or hanger.

When my invention is applied to a wagon its body is removed and thecross baiI 11 carrying the fulcrum supports or n'ieinbers 10 arearranged upon the bolsters and secured to them by set screws 12. Thebody then replaced upon the running gear so that it rests upon the crossbars 11 between the stakes 6, as shown in Fig. 5, it being noted thatthe engagement of the cleats 7 with the cross bars 11 prevents endwisemovement of the body.

`When it is desired t0 weigh the contents of the bodyI the levers 9 areengaged with the fulcrum supports 10, and then engaged with the couplingmembers 2O after the latter have been arranged upon the pivots 21. Thehook 30 of the fulcrum support of th(` lever S is then engaged with oneside of the body 2 and the hooks 48 then engaged with the other side ofthe body to support the hanger 46 and the scale beam. The rods 25 arethen engaged in their' hangers 26 and the cross bars 29 are attached tothe body 2 above said rods. The screw jacks are then adjusted so thatthe body 2 will be elevated when the weights are manipulated upon thescale beam in the act of weighing.

From the foregoing it will be seen that by constructing the severalparts of the invention as above described they will 'be strong anddurable and may be produced at a coinparatively small cost. Thepeculiar' construction of the several parts also enables them to berapidly removed. and disassembled so that the weighing of the contentsof the wagon may be quickly and easily aecomplished. By permitting ofthe removal of all parts of the device except the fulcrum supports, theliability of breakage is reduced to a minimum and there will be nothingto interfere with the use of the wagon in the usual manner.

Vhile I have shown and described in detail the preferred embodiment ofmy invention I wish it understood that I do not limit myself to theprecise construction set forthI and that various changes in the formIproportion,'and minor details may be resorted to without departing Jfromthe spirit or sacriiicing any of the advantages of the invention. l
